HMI Development on Intelligent Displays

4dsystems_HRES4D Systems and Future Technology Devices International Limited (FTDI) (aka, FTDI Chip) recently introduced the 4DLCD-FT843. The intelligent display solution incorporates FTDI Chip’s FT800 Embedded Video Engine (EVE) with the subsequent introduction of two additional products. This combined product gives design engineers a foundation on which to quickly and easily construct human-machine interfaces (HMIs).

The first of these products is the ADAM (Arduino Display Adaptor Module). This 47.5-mm × 53.4-mm Arduino-compatible shield permits communication between the Arduino via the SPI. The shield is suitable for use with Arduino Uno, Due, Duemilanove, Leonardo, Mega 1280/2560, and Pro 5V. The shield’s micro-SD card provides the Arduino-based display system with ample data storage. The 4DLCD-FT843 can use the micro-SD card to retrieve objects (e.g., images, sounds, fonts, etc.). Drawing power from the Arduino’s 5-V bus, the ADAM regulates the 4DLCD-FT843’s supply to 3.3 V. The FT800 EVE controller can handle many of the graphics functions that would otherwise need to be managed by the Arduino.

The ADAM is complemented by the 4DLCD-FT843-Breakout. With a 26.5-mm × 12-mm footprint, this simple breakout module enables the 4DLCD-FT843 to be attached to a general host or breadboard for prototyping purposes. It features a 10-way FPC connection for attachment with the 4DLCD-FT843 along with a 10-way, 2.54-mm pitch male pin header that enables it to directly connect to the host board. Both products support a –10°C-to-70°C operational temperature range.

The EVE-driven 4DLCD-FT843 has a 4.3” TFT QWVGA display with a four-wire resistive touchscreen. It features a 64-voice polyphonic sound synthesizer, a mono PWM audio output, a programmable interrupt controller, a PWM dimming controller for the display’s backlight, and a flexible ribbon connector.
